Charger shows E11; internal self-test reports current measurement or calibration error.

Safety first: Do not continue using a charger that cannot correctly measure current; this can defeat safety limits.

• 1. Reboot and update firmware:
  • Disconnect from mains and vehicle, wait 2–3 minutes, then reconnect.
  • Use the NRGkick app to check for firmware updates and apply them.
• 2. Observe behavior:
  • If E11 appears immediately on power-up, the sensor or its wiring is likely defective.
  • If it appears only under load, overheating or intermittent connection may be involved.
• 3. Do not bypass limits:
  • Avoid any attempt to override current limits or use external timers to force operation.
• 4. Service action:
  • Current sensors are mounted on the power board and require disassembly to replace.
  • Contact NRGkick support for board-level repair or replacement.
